Here is your answer please mark me as brain list please

Answer 2

Answer :

• Volume of hemisphere is 718.6cm³

Given :

• Diameter is 14cm

To find :

• Volume of a hemisphere

Solution :

Given Diameter is 14cm

• Radius = 14/2 = 7cm
• Radius is 7cm

As we know that ,

• Volume of hemisphere = 2/3 πr³

where r is 7cm

⟶ v = 2/3 × 22/7 × 7³

⟶ v = 2/3 × 22/7 × 7 × 7 × 7

⟶ v = 2/3 × 22/7 × 343

⟶ v = 718.6cm³

Hence , Volume of hemisphere is 718.6cm³

More Explanation :

• Volume of hemisphere = 2/3 πr³
• surface area of hemisphere = 2πr²
